Title: Hydraulic clutch
IPC: F16D31/04
Filed: 1955-01-14
Abstract: 764,416. Hydraulic clutches. WICKMAN, A. C. Jan. 14, 1955, No. 1171/55. Class 69 (2). An hydraulic clutch comprises a pump and a reservoir, flow through the pump being controlled by a valve responsive to a centrifugal governor. An hydraulic clutch comprises a geartype pump having planet gears 13 mounted in a driven casing and meshing with a sun-gear 14 on an output shaft 15. Partitions 11, 19 in the casing separate the pump from a reservoir, the partition 11 having inlet ports 18 and outlet ports 16, 17, and partition 19 having inlet and outlet ports corresponding to, but angularly offset from, those in the partition 11. A disc valve 23 controls communication between the ports. The volume of liquid in the reservoir is such that when the casing is rotated the centrifugally formed fluid ring covers the inlet ports and the outlet ports communicate with the central air space. The disc valve 23 has helically splined engagement with a sleeve 29, angular position of which is controlled by a centrifugal governor. At idling speeds the pump inlets are closed and the outlets partially open so that no drive occurs. At intermediate speeds throttled flow through the pump is permitted, and at greater speeds the inlet ports are partially open and the outlets closed so that the pump rotates solid. When used in a vehicle transmission the clutch may be disengaged to permit gear changing by moving the sleeve 29 axially to the right, thus rotating the valve 23 through the helical splines to a position in which the inlet ports are closed and the outlet ports are open. Sleeve 29 is prevented from axial movement during idling by a ring 35, having notches which are offset from teeth 36 on the sleeve under idling conditions.

Title: Separation of components of coal tar fractions
Inventor: WADDINGTON WRIGHT
IPC: C10C1/18
Filed: 1961-01-12
Abstract: A method of fractionating coal tar or coal tar fractions comprises extracting the tar or tar fraction in a first stage with a mixture of water and acetic acid in a first stage, the material remaining after extraction, or the extract, then being extracted with a mixture of water and acetic acid in different proportions. The first or second extraction may yield a substantially binary residue which is extracted with a mixture of acetic acid and water in still different proportions to resolve the residue into its components. In one form the tar is fed successively through first, second, and optionally third stages in which it is extracted with acetic acid-water mixtures in corresponding different proportions, the mixture for one stage being obtained by adjustment of the proportion of the water and acetic acid in an extract from a next stage, with concomitant liberation of the extracted component. The Provisional Specification is not restricted to the use of acetic acid-water mixtures, but refers generally to mixtures of two liquids which are completely miscible in all proportions, so chosen that the compounds are almost insoluble in the one and almost completely soluble in the other.

A dressing tool for an abrasive wheel 18 comprises a dressing element 6, Fig. 4, slidably mounted on and projecting from a carrier 1 having guide means 12 to coact with a workpiece rest 16. The dressing element, such as a diamond, isc cemented to a spindle 5 formed with a screw-threaded portion 7 by means of which the dressing element is adjustable relative to the carrier, the spindle is held in its adjusted position by a friction pad pressed against the spindle by a grub screw 14. The guide means consists of a bar 12 which is adjustably secured to the carrier by bolts 11 passing through slots in the carrier. In operation, the bar is pressed against the workpiece rest 16 on the machine while the dressing element is traversed across the wheel 18. After each traverse, the element is advanced a small distance by rotation of the spindle. In an alternative embodiment, the spindle 25, Figs. 7 and 8, is disposed in a bore inclined to the base of a body 22 adjustably secured by bolts 34 passing through slots 39 to an inclined portion 31 of a plate 30 having a guide bar 33 adjustably secured thereto by bolts 32. The axis of the spindle 25 carrying the diamond 26 is thus inclined to the horizontal plane to provide the diamond with a trailing action in the direction of movement of the surface of the grinding wheel and can be adjusted to a similar angle from a plane normal to the axis of the grinding wheel to provide the diamond with a trailing action as it is traversed across the wheel. The body 22 may be pivotably mounted so that it is free to automatically move to one side or the other of the plane normal to the axis of the wheel and provide a trailing action in both directions of traverse across the wheel ; a spring may provide a snap-over action for the movement of the body. The body 22 may be used without the plate 30, a guide bar being secured to the body by bolts passing through the slots 39.

Title: An improved method and apparatus for coating ices
IPC: A23G9/24
Filed: 1948-01-17
Abstract: 641,577. Coating ice cream. SAXON, A. Jan. 17, 1948, No. 1490. [Class 28(i)] Ice cream slabs are coated with chocolate by placing the previously cut slabs in the compartments 23 of a loader 11, pushing the spikes 17 of a carrier frame 16-18 into the spaced slabs and then transferring them on the carrier into a coating tank 12. The frames are then hung up on rack bars 15 over the tank 12 to drain and set. The slabs are then stripped from the spikes by pushing the carrier frame down into a channel 28, the flanges 29 of which hold the blocks while the spikes move down and out. The coated blocks are then removed for wrapping. The bottoms of all compartments 23 in the loader 11 are sloped at 26 so that the ice slabs, which may be narrower than the compartment, lie up against the same side of each partition 24 to space them evenly for engaging the spikes 17 and allow the liquid chocolate to flow between them when immersed. The loader 11 is removably secured to the table by keyhole slots. Back compartments of the loader 11 may be used for slabs which are too thick for the front compartments 23, the slabs being placed and held against the back by the incline 27, Fig. 3, and spaced by shallow back ribs 25. The same spiked carrier may be used. The carrier 16 may have upstanding hooked ends 18, one of which carries a short inverted channel piece 20 to hook and slide over horizontal rails 15. An operator at the loader end of the table hooks each carrier with the freshly dipped slabs on his end of the lower rail 15, each succeeding carrier pushing the previous carrier to the removing end where another operator removes them and places each empty carrier channel 20 on the higher rail 15, each being pushed along on the rail to the loading end by the succeeding carrier 16 for re-use.

Title: Chuck for machine tools or the like with jaws controllable during the working of the machine
IPC: B23B31/163
Filed: 1940-01-26
Abstract: 538,367. Chucks. EVANGELISTA, M. Jan. 26, 1940, Nos. 1671, 1672 and 1673. Convention dates, Jan. 31, 1939, Nov. 10, 1939 and Nov. 24, 1939. [Class 83 (iii)] A chuck having jaws controllable during running has a casing 5 in which is mounted a sleeve 9 carrying a scroll plate 8 which actuates the jaws 7, and external control being connected by two sets of planetary gearing arranged between the casing and the scroll plate to operate the chuck. The sleeve 9 carries a bevel gear 10 engaging planetary bevels 11 carried by arms 16 connected with a worm wheel 17. The bevels 11 also engage one side of a double bevel wheel loose on the sleeve 9 and engaging on the other side planetary bevels 13 coacting with a bevel wheel 14 secured to the casing. The bevels 13 are mounted on carrier arms 20 connected to a stationary ring 19 carrying a worm 18 engaging the wheel 17. Normally the wheel 14 on the casing and the wheel 10 on the scroll-plate sleeve both rotate at the same speed and the planet carriers are stationary. By rotating the worm gearing 18 in one direction or the other the carrier of the planets 11 is rotated and the scroll plate is advanced or retarded relative to the casing to open or close the chuck. In a modification Fig. 2, the chuck body 5b on which the jaws are guided is carried on a spindle 26b driven by a gear 27b. The scroll plate 8b is connected through planetary gears 11b...11<SP>111</SP>b carried on shafts mounted in the fixed frame 25b to a loose wheel 12b on the spindle, this wheel being further connected through planetary gears 13b ... 13<SP>111</SP>b mounted in a rotatable casing 17b to a wheel 14b fixed on the spindle. In normal operation the scroll plate is driven at the same speed as the chuck body but by rotating the casing 17b through worm gearing 18b the scroll plate is accelerated or retarded to adjust the jaws. In a modification of this form the gear 12b is replaced by an internal gear so that the use of reversing pinions 13<SP>1</SP>b and 11<SP>1</SP>b is avoided. In a further modification the gears are of conical form. In another modification, Fig. 6, adapted to be fixed to a machine spindle by a flange 28e the flange is connected to a short hollow shaft 29e connected to the jaw carrier 30e. The casing 5e may be adjustably fixed by a stem 31e. Teeth on the member 29e are engaged by a planet bevel 13e mounted in a ring 38e and connected through a loose double gear 12e and bevel gear 11e to a bevel ring 42e secured to the scroll plate. The casing carries a loose ring 35e which may be rotated by a lever 36e having a spring plunger 38e adapted to engage one of a series of holes in the ring 33e to rotate the ring to operate the jaws.

Abstract: 405,958. Controlling change - speed gearing. WILSON, A. G., 23, Queen Anne's Gate, London. May 5, 1932, No. 1788/34. Divided on 405,664. [Class 80 (ii).] Relates to means for braking reaction drums in changespeed epicyclic gearing especially of the Wilson type and as applied to vehicles. Each reaction drum 1 is gripped by pairs of rings or pairs of sets of pads so that the braking thrusts are balanced and do not displace the drum. Thus coned rings or pairs of pads 3, Fig. 2, supported on non-rotary frame arms 3a are separated into gripping engagement with twin cones 12 on the periphery of the drum 1 by the angular displacement of a control ring 5a. Each pair of grip elements 3 is threaded on a right and left handed screw 4 with a lever arm 5 engaging the ring 5a so that displacement of the ring operates all the grip elements in unison. An arrangement is described with the cones 12 arranged the other way, back to back. In Fig. 3, the drum 1 is shown with a peripheral flange 8 adapted to be gripped between a pair of brake rings 7 held against rotation by frame arms 7a. The brake is applied by displacing angularly outer saw-tooth cam rings 10 by suitable connecting and controlling means 9. Specifications 164,042 and 312,128, [both in Class 80 (ii), Gearing, Variable-speed &c.], are referred to.

Title: Improvements in or connected with balance centreing apparatus associated with means for drilling centreing holes on rotating bodies
IPC: G01M1/04
Filed: 1952-01-23
Abstract: 744,662. Electric indicating systems. AVERY, Ltd., W. & T. (Schenk Maschinenfabrik, Ges., C.). Jan. 20, 1953 [Jan. 23, 1952], No. 1823/52. Class 40(1) [Also in Group XXII] In a balance centring apparatus of the kind described in Specification 715,764 for drilling centring holes on the inertial axis of a rotating 'body to locate subsequent machining operations, wherein the body is carried on adjustable bearers of a rotating cage within which it may be adjusted for dynamical balance about an axis normally coincident with the axis of the cage and the centring drills, means are provided for displacing, prior to balance centring, the inertia, axis of the rotating body by a pre-determined distance relative to the rotational axis, to compensate for asymmetry introduced by subsequent machining operations, whereby the finished body is substantially dynamically balanced. Figs. 1, 2 show a workpiece 16 (e.g. a crankshaft) mounted for balancing between positioning devices 17, 18 and spring- loaded pins 19, 20 of a cage structure comprising end discs 3, 4 connected by rods 5. 6, 7 and rotatable on hollow axially aligned shafts 8, 9 surrounding drills 10, 11 driven by motors 12, 13, which shafts are carried in oscillating journals 14, 15 so that the workpiece is adjustable to a dynamic balance position within the cage for centring holes to be drilled as set forth in the Specification above referred to. Each end disc carries weights 21, 22 in quadrature positions as shown at 22, 22a, in Fig. 3, capable of radial adjustment by screws 23, 24, 26 having pointers movable relative to calibrated scales, whereby the inertia axis 33 of the rotor may be displaced relatively to the axis of rotation prior to the balance centring operation so that the centres are drilled in positions offset from true balance. In operation, a number of rough sample workpieces are taken from a series production run, balance centred on their inertia axes as set forth in the Specification referred to, fully machine finished, and re-balanced to determine the magnitude and position of the residual unbalance when finished. The average value of unbalance is then determined, and compensated by adjustment of weights 21, 22 of the balance centring machine as described with reference to the calibrated scales, so that the machine may be used to accurately centre each rough workpiece of the production run for apparent coincidence between the inertia axis and the rotational axis of the cage and workpiece assembly, but with an inherent unbalance moment such as to compensate for unbalances introduced by further machining, whereby the final product is substantially balanced. A weight 34 may be added to each end disc to compensate for the intrinsic unbalance of an asymmetrical workpiece (e.g. an eccentric) which is to be processed.
